In my previous article (What’s next after Defi and NFTs) we discussed how Bridge Solutions can bring in a new era of interoperability among blockchains. As blockchain becomes more popular, people will spread to multiple blockchains using the dapps of their choice. The forced upon platter by the influencers will no longer be there, knowledge will be evenly distributed. Barriers will be broken and entry will be easier.
Darwinia – A Model Interoperability Solution
I will explore one interesting interoperability protocol which I came across and I believe can be a good model to demonstrate how future bridge solutions will look like. Darwinia Network is using the substrate as its core technology. In a nutshell, the Darwinia Bridge chain will be able to bridge with any chain (currently Ethereum, Tron, Heco, and Kusama) and provide interoperability. Such interoperability can be in any direction.
It is trying to target both institutions and retails customers. The institutions will be able to transfer their project assets (tokens, nfts) to their implementation in another blockchain. Such projects might not create their bridge solution, (which sometimes becomes an overhead) but can use Darwinia’s hub tech. For the retail customers imagine you can play a single game on any blockchain without the need to move between chains. Darwinia is developing a game called Evolution Land. Players from Ethereum or Tron (or any other blockchain) can play this game simultaneously.
Darwinia – A Guide
Darwinia has 2 tokens. The native token is called RING. This is used to pay Gas for transactions. KTON is a secondary token that is provided as a reward to long-term stakers. For now, we will just focus on RING.
RING can be purchased in Huobi Exchange or can be swapped with other tokens in Uniswap. It is better to buy in Uniswap, as sending RING from Huobi to Metamask takes up a considerable amount of Gas fees. Ideally, with the concept of Bridge solutions, you will not need an exchange to transfer tokens.
Use this link to access Darwinia wallet. It can be easily integrated with your Polkadot.js extension.
Your wallet address will be shown in the top right, else you can create a new account using Add account in the top right.
Copy your account number.
On the left bar of the wallet, scroll down, and click on Wormhole. This is the bridge UI that will help you in token transfer.
A wormhole is a wonderful tool where like gameplay you will be able to select the bridged networks. This is the picture you need to have in mind for the future. This will expand to multiple blockchains and all will be interconnected.
I will move RING from Uniswap to Darwinia wallet. So I will choose Ethereum and Darwinia and click on cross-chain transfer. See the direction of the arrow.
Cross-check the chain again (Ethereum -> Darwinia Mainnet) and click on Cross-Chain transfer. Ensure that your Metamask is enabled.
Enter the destination Darwinia Mainnet account and select the amount of Ring you want to send. Currently, the cross-chain transfer fee is 10 RING. Approve the transaction in your Metamask (unfortunately, you will have to pay Ethereum Gas fees in this case).
Darwinia shows a status bar for your transaction. Soon you will see that the Ethereum confirmation has been completed. Immediately after that, the Chain Relay needs to be confirmed. This takes a longer time (ideally 20-25 minutes).
After that specific period, you will have the RING in your Darwinia wallet.
This same process is applicable in between other chains which are enabled currently.
The current adoption is low. The project is still a work in progress. But with the amount of work which is done till now, it seems that the potential is huge. A project which can lead to the growth of a new sector.
